1941 CATALOGUE OF FISHES OF TORTUGAS ,5 



nomenclature of genera has been adopted herein, did not see fit to follow Parr. 

 It is evident from the present study that closely related species differ in the size 

 of the mouth, and that there may be considerable variation within a species (see 

 under C. macrops). S. F. H. 



Etropus rimosus Goode and Bean 



Two poorly preserved specimens, 90 and 92 mm. long, without definite data, 

 belong here, as shown by comparison with the type (U. S. Nat. Mus. no. 37332). 

 Though the scales on the body are lost, strongly ctenoid ones remain on the 

 snout. The pectoral on the ocular side is notably the larger and longer, a fact not 

 stated in descriptions consulted. 



The color of preserved specimens is grayish. The only marking evident is an 

 obscure dark blotch in lateral line about an eye's diameter in advance of end of 

 bases of dorsal and anal, which is present also in the type. 



The following proportions and enumerations are based on the 2 Tortugas 

 specimens: Head 4.35, 4.45; depth 2.0, 2.0; pectoral (ocular side) 4.5, 4.7. Eye in 

 head 3.3, 3.4; snout 6.6, 6.8; maxillary 4.5, 4.6; caudal peduncle 1.85, 2.0. D. 77, 

 81; A. 61, 62; P. 10, 10 on occular side, 8, 8 on blind side; scales (pockets) 39, 41; 

 gill rakers 6, 6 (only 5 in type). 



Gulf of Mexico. S. F. H. 



Trichopsetta ventralis (Goode and Bean) 



Thirty-three specimens, 89 to 228 mm. long, were taken in nine hauls in 40 to 

 100 fathoms. 



D. 89 to 93; A. 70 to 74 in 4 specimens. P. 8 or 9 on blind side, 12 on other side; 

 scales 66 or 67 in 3 specimens. 



Very delicately colored with palest of gray, faintly tinged with yellow; body 

 and fins dotted sparsely with darker gray, the markings commonly consisting of 

 circles varying from less than size of pupil to size of eye; a larger, darker, and 

 more irregular spot at anterior end of straight part of lateral line. 



The male is distinguished by the elongated right ventral, and a dark spot on 

 the anterior part of the anal fin.

Engyophrys sentus Ginsburg 



Engyophrys n. sp. Longley, Carnegie Inst. Wash. Year Book No. 30, 1931, p. 386 — Tor- 

 tugas, Florida (listed without description). 



Engyophrys sentus Ginsburg, Proc. U. S. Nat. Mus., vol. 82, art. 20, 1933, p. 6 — off Dry 

 Tortugas, Florida, in 50 fathoms. 



About 24 specimens, 75 to 100 mm. long, were taken in 43 to 65 fathoms. 



In 5 examined the fin formulas are, D. 73 to 82; A. 60 to 64. In a specimen 100 

 mm. long, 88 mm. standard length, the head measures 18 mm. (4.9), depth 48 

 mm. (1.8), and eye 5.0 mm. (3.6 in head). Maxillary short, not reaching eye; 

 teeth in both jaws on blind side only, in single series, small and close-set, inclined 

 inward; none on vomer or palatines; gill rakers very small, 4 to 6 on lower limb 

 of first arch; 3 preorbital spines on left, 2 on right; interorbital ridge narrow,
